OS: Windows 10 ver. 2004, build 19041.338
Affected product: Affinity Designer 1.8.4.693 (non Microsoft store version)
Hardware: Microsoft Surface Book 1st Gen (i5 6300u, 8gb ram, 256gb ssd) Microsoft Surface Pen (battery level 61%)
Issue: When dragging nodes/lines or when resizing objects in Designer while using pen input the line/object/indicator will glitch and flash rapidly.
More info: This issue first appeared for me after upgrading to version 1.8.4.693, it was not present in the earlier version i was using but that version was out of date and i do not know the version number. I believe the build i was using was installed around March this year. This issue does not seem to be present in Affinity Photo, i did not test in Publisher. The issue is only with pen input, both mouse and touch inputs seem unaffected at this time. General drawing and other activities are unaffected by the glitching. This happens on both new and current projects. The issue is present in all performance modes for the laptop, from power save to full performance mode while plugged in. This issue still occurs when a different Surface pen is used. As a troubleshooting step, all user settings were reset to default by holding CTRL on startup, issue still present.
Here is a video of the issue, i apologize for the quality and terrible audio. Please mute or turn down before viewing.
